I had sex with my boyfriend about one to two days after I got off my period for the first time. I have been on Loestrin 24 Fe for around two years now because I have endometriosis and have severe cramps and irregularity. We also used a condom and he pulled out before ejaculating into the condom. Since then I have been having stomach cramps, back pain and today, a week exactly from when we had sex, I've had light brown discharge. I'm expected to ovulate around today as well. I am absolutely terrified of getting pregnant. My boyfriend assures me that there is no way I could be pregnant. I just am freaking out because of the cramps and brown discharge. My period is not due until around October 13 according to my period tracker, and I'm ending my first week of birth control pills for this month
